SYRINGE- NozzLE.

SPECIFICATION forming part of Letters Patent No. 565,928, dated August18, 1896.

Application tiled January 22, 1895. Serial No. 535,836. (No model.)

To all whom it m/tz/ concern.-

Beit known that I, HENRY RSCQTT, a citizen of the UnitedStates,.residing at Kansas City, in the county of Jackson and State ofMissouri, have invented certain new and useful Improvements in VaginalSyringes, of which the following is a specification, reference being hadtherein to the accompanying drawings.

My invention relates to improvements in vaginal syringes, particularlyto the class of syringes in which .the nozzle is provided with aninclosing frame adapted to distend the walls of the vaginal canalpreparatory to the injection.

The object of my invention is to provide a syringe-nozzle with anexpansible inclosing frame which may be folded upon the nozzle wheninserting into or withdrawing from the vagina and expanded when in use,so as to distend the vagina during injection.

My invention consists, further, in certain peculiarities of constructionfully described hereinafter. n

In the accompanying drawings, illustrative of my invention, Figure lrepresents an elevation view of the nozzle and frame with the frameexpanded. Fig. 2 represents an elevation view of nozzle and frame withthe frame contracted. Fig. 3 represents a modifled form, in perspective,of the clampingcollar. Fig. 4 represents a top view of the nozzle andframe, showing the frame eX- panded. Fig. 5 represents an elevation viewof the lower end of the nozzle. Fig. 6 represents in ,elevation amodilied form of collar. Fig. 7 represents a plan view of the form shownin Fig. 6. Fig. 8 represents a top view showing the frame closed.

Similar letters of reference indicate similar parts.

Referring to the drawings, A indicates the nozzle, of the ordinarypattern and made, preferably, of hard rubber. The nozzle is providedwith a longitudinal central opening extending from the lower end to theopenings (indicated by C) near the upper end. These openings arecircumferentially disposed and preferably open downward, so that the injected iiuid will tend to carry any foreign or injurious matter downwardtoward the vaginal orifice. The frame B is preferably made of wire arms,vertically disposed around the nozzle, each lying in a vertical planeradially disposed with reference to the nozzle when the frame isexpanded, as illustrated in Figs. l and 4, and when closed, as shown inFig. 8, the arms of the frame each lie in a vertical plane obliquelydisposed with reference to each other. The upper ends of the wire armsof the frame B are curved inwardly and then downwardly, each oneentering and revoluble in a vertical opening in the top of the nozzle,the said openings being radially arranged near the periphery of theAnozzle. The lower ends of the arms of the frame B are secured each in avertical recess J, Fig. 3, of a split ring or collarE. The ring orcollarE is made of resilient material, such as brass, and of a size`such that it may be sprung upon the hub D of the nozzle, the lower endof the hub being preferably tapering inwardly and downwardly, asindicated by E. It is desirable to have the collar tapered to correspondto the taper of the hub E. It is not essential to the invention to taperthe collar and hub, as the resilience of the collar will ordinarily holdthe collar well secured to the nozzle. A small depression is made on theinner side of the collar E, as indicated by G, which is adapted to acircumferential groove I in the periphery of the hub E. This groove inthe hub is so arranged that when the collar E is turned to a positionthat the wires of the frame B lie in radial \planes the depression Gstrikes against the end of the groove at the left.

Ordinarily the depression G is simply a circular depression in themetal, but it may be varied in form, as indicated in Figs. 6 and 7, inwhich form the depression is rectangular, one end and the sides beingcut through the metal. The lower end of the nozzle is provided with amilled flange F.

H indicates the part to which the rubber tube of the syringe fastens.

In using my invention the portion H is secured in the ordinary manner toa syringe. The collar E is then turned to the right, carrying with itthe lower ends of the wires of the frame B, until the frame assumes theshape shownlin Figs. 2 and 8. The nozzle is then inserted in the vagina,after whichvthe collar E is turned to the left until the depression Gcornes in contact with the end of the ICO groove I, at which time theframe is expanded into the shape shown in Figs. l and 4. The

vaginal walls are now distended, so that the washing may be thoroughlyperformed. In withdrawing the nozzle the collar E is turned to theright, closing the frame and permitting its easy withdrawal from thevaginal canal. Variations may be made from the construction shownwithout departing from the spirit of my invention, as, for instance, inusing a complete ring of the proper resiliency instead of a split ring.

Other means than those shown for folding and opening the frame maybeused. It may be expedient also to obtain an opening and closing effectof the frame by revolving the collar E in a direction opposite to theone shown. The same opening and closing effect may be obtained by`revolving the nozzle A in the proper direction instead of the collar E.For a better washing effect it is someti mes desirable to have alternateopenings C, opening upward instead of downward. The invention may alsobe operated without using the opening and closing features in someinstances, in which event it may be used in either the open or closedposition.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. In a syringe, the combination with a nozzle, of a series oflongitudinal arms arranged around the nozzle, an eXpansible collarencircling the nozzle and revoluble thereon and having secured to it thelower ends of the said arms the upper ends of which are curved inwardlyand are pivotally connected with the upper end of the nozzle, and 'meansfor preventing longitudinal movement of the colv lar upon the nozzleduring use, substantially as described.

2. In a syringe, the combination with a nozzle having two shoulders nearits lower end, of a series of longitudinal arms arranged around thenozzle, and pivotally connected to the nozzle at its upper end, adivided springeollar encircling the nozzle between the two shoulders andrevoluble thereon and having secured to it the lower ends of the saidarms, substantially as described.

3. Ina syringe, the combination with a nozzle having a series ofopenings in its upper end near its periphery, of a series oflongitudinal arms arranged around the nozzle and having their upper endspivoted in the said openings, a divided spring-collar encircling thenozzle and to which the lower ends of the arms are secured, and havingan inwardly-extending projection engaged with a groove in the nozzle,whereby circumferential movement of the collar upon the nozzle ispermitted but longitudinal movement thereon prevented unlessthe collaris expanded, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
